This sound comes from League of Legends, Riot Games' multiplayer battle arena released in 2009. The in-game announcer uses it when a player secures two kills close together, making it one of the most recognizable kill streak calls in online gaming. Over time it spread far beyond LoL into montage culture, short gaming clips and meme edits, where it still works as a fast shorthand for a doubled result. It is often grouped with other arcade-style cues such as hitmarker sounds and Monster Kill lines.
